Outlook on the 2026 House Elections: Recent Developments in the Contest for House Control
Notable Shifts Since the Start of 2026
Since the end of 2025, the outlook for control of the House in the 2026 midterms has shifted significantly in favor of Democrats, who now maintain a notable advantage in generic ballot polling and overall race ratings. While Republicans entered President Donald Trump’s second term on a political high with a unified government, the landscape has become increasingly challenging for the GOP due to slipping presidential approval ratings and backlash against administrative policy maneuvers.
As a reminder, the 2026 House midterm elections center on a volatile, razor-thin margin where Republicans are defending a narrow majority. All 435 House seats are up for election in 2026. Republicans currently hold 218 seats compared to 214 seats held by Democrats, leaving the GOP with just a one-seat majority for now and little room for party disunity.
There are currently three vacancies in the House for the seats previously held by former Rep. Marjorie Taylor Greene (R-GA) who resigned her seat in January, now-New Jersey Governor Rep. Mikie Sherrill (D-NJ), and the late Rep. Doug LaMalfa (R-CA). Special elections have been scheduled on March 10 in Georgia’s 14th Congressional District, April 16 for New Jersey’s 11th Congressional District, and August 4 in California’s 1st Congressional District. None of these three vacant seats are expected to flip in the upcoming special elections, as each district remains a stronghold for the party that held the seat previously.
Control of the lower chamber in the 120th Congress will hinge on a relatively small universe of competitive seats. Just a handful of districts remain at the center of national attention, particularly those where incumbents underperformed in 2024, where redistricting has altered the playing field, or where open seats have created an environment conducive for competitive campaigning.
Many Republicans in Washington seem increasingly resigned to the fact that retaining the Speaker’s gavel will be an uphill fight. History is certainly not on their side, as time and time again governing majorities with small margins have seen major gains by the opposition party in a midterm year. Regardless, a GOP strategy is emerging that seeks to label Democratic challengers as radical and embrace proximity or distance from the president as it makes sense in individual districts.
Though their momentum appears to be building, Democrats must still be thoughtful about their approach if they aim to control the chamber in 2027. While Democratic candidates are striving to capitalize on Trump’s declining popularity and high voter enthusiasm, overall, the party continues to lack a significant financial advantage and struggles with donor fatigue as the midterm cycle kicks into high gear.
Observations on the Electoral Environment
As noted above, we have recently seen improvements in Democrats’ performance in generic ballot polling, with the latest polls showing Democrats with an advantage of three to seven points. This is a departure from the dead heat we saw between Democrats and Republicans in generic ballot polling just ahead of the last House elections in November 2024. Additionally, last month, one leading political pundit – the Cook Political Report – shifted 18 House races towards Democrats. Of the 18 tossup races identified by Charlie Cook, 14 seats are currently held by Republicans, meaning the GOP would need to win roughly three-quarters of these to maintain its House majority.
There is additional evidence to suggest that Democrats might feel like they have the wind at their backs. Earlier this month, the Democratic Congressional Campaign Committee (DCCC) added five more Republican-held seats – those currently held by Reps. Jeff Crank (R-CO), Brad Finstad (R-MN), Ryan Zinke (R-MT), John McGuire (R-VA), and Nancy Mace (R-SC) – to its list of Districts in Play for the 2026 cycle. These additions brought the total number of seats Democrats are focused on flipping from red to blue to 44. Just this week, the DCCC also announced the first dozen candidates in its Red to Blue program. Notably, the House Democratic campaign arm plans to invest resources in districts that President Trump won in 2024 by as much as 18 points, expanding its reach beyond the districts traditionally targeted for a flip. Of the 12 Red to Blue seats announced so far, Trump won three of these districts by double digits in the last cycle. The median district voted for the president by 8.5 points.
The 2026 electoral map continues to be shaped by a growing number of retirements. As of mid-February, 51 sitting Members of the House – 30 Republicans and 21 Democrats – announced they will not seek reelection to their current seats in the 2026 midterm elections. This wave of departures is considered a modern record at this point in the election cycle. Of these departing incumbents, 24 are retiring from public office, 15 are running for Senate, 11 are running for governor, and one is running for state attorney general. Historically, a higher number of departures for the incumbent party increases the party’s vulnerability in open-seat contests.
While President Trump’s name will not appear on the ballot, his declining job approval ratings could shape the outcomes in 2026 House races. Recent polling has captured the president’s approval rating hovering between 36 percent and 37 percent – just above his all-time low of 34 percent recorded at the end of his first term following the January 6 attack on the Capitol. Compared to other modern presidents, Trump’s approval ratings are significantly lower at the one-year mark of a second term. This could spell bad news for Republicans considering that President George W. Bush lost 30 House seats in the 2006 midterm elections and President Barack Obama lost 13 seats in the House in 2014.
Update on Redistricting Efforts
Another factor that cannot be ignored is continued progress on mid-decade redistricting. While many redistricting efforts were spearheaded by Republicans seeking partisan advantages, analysts now suggest redistricting may do little to safeguard the Republican House majority. To date, five states have enacted new Congressional maps that will be used in the 2026 midterm cycle:
California: Back in November, California voters approved Proposition 50, temporarily overriding the state’s independent commission and allowing the legislature to redraw the map. The new boundaries could help Democrats flip as many as five of California’s 52 Congressional districts. The seats currently held by incumbent Reps. Kevin Kiley (R-CA), David Valadao (R-CA), Ken Calvert (R-CA), and Darrell Issa (R-CA) are most likely to be impacted, along with the vacant seat previously held by Rep. LaMalfa.
Missouri: In September, the Missouri legislature advanced a Republican-backed map during a special legislative session called by Gov. Mike Kehoe. The map seeks to increase the Republican advantage from a 6-2 split to a 7-1 split in Missouri’s eight House seats. The new plan significantly alters the 5th Congressional District currently represented by Rep. Emmanuel Cleaver (D-MO) by splitting Kansas City into three separate GOP-leaning districts.
North Carolina: The state’s general assembly adopted a new Republican-favored map in October for use in the midterm elections. The new map was designed to flip the 1st Congressional District currently held by Rep. Don Davis (D-NC). If Republicans are successful, this could result in a delegation of 11 Republicans and 3 Democrats, a shift from the current 10-4 split.
Ohio: In late October, the Ohio Redistricting Commission unanimously approved a new map, increasing the Republican advantage from a 10-5 split to a projected 12-3 split across the state’s 15 districts. Ohio’s 1st Congressional District, held by Rep. Landsman, and the 9th Congressional District, represented by Rep. Marcy Kaptur (D-OH), now lean more Republican. Meanwhile, Rep. Emilia Sykes (D-OH) will run for reelection in a new 13th Congressional District that is slightly bluer.
Texas: Under pressure from the Trump Administration, Texas became the first state to pursue mid-decade redistricting back in July 2025. A December Supreme Court stay confirmed that the redrawn map will be used in the 2026 midterm elections. The map is engineered to allow Texas Republicans to flip five seats, increasing their control to 30 of the state’s 38 Congressional districts. The districts reshaped to become more competitive for GOP candidates include Texas’ 9th Congressional District currently represented by Rep. Al Green (D-TX), the 28th Congressional District held by Rep. Henry Cuellar (D-TX), the 32nd Congressional District represented by Rep. Julie Johnson (D-TX), the 34th Congressional District currently held by Rep. Vicente Gonzalez (D-TX), and the 35th Congressional District represented by Rep. Greg Casar (D-TX).
Six additional states have alterations to their maps planned or pending:
Florida: The state is moving towards a mid-decade redistricting of its 28 House seats for the 2026 elections cycle, with a special legislative session scheduled in April to redraw Congressional boundaries and the candidate filing deadline already pushed into June to accommodate the new map. Florida Republicans are reportedly eyeing a net gain of three to five seats, most likely in Central and South Florida. Districts that might be targeted to create more electoral opportunities for Republicans include Florida’s 9th Congressional District, currently held by Rep. Darren Soto (D-FL), the 20th Congressional District represented by Rep. Sheila Cherfilus-McCormick (D-FL), Florida’s 22nd Congressional District held by Rep. Lois Frankel (D-FL), the 23rd Congressional District represented by Rep. Jared Moskowitz (D-FL), and the 25th Congressional District held by Rep. Debbie Wasserman Schultz (D-FL).
Louisiana: Louisiana will use its 2024 Congressional map, which features two majority-Black districts out of six, in the 2026 midterms. This represents a change from the single majority-Black district used in 2022, with Louisiana’s 6th Congressional District – a safely Republican seat previously held by now-retired Rep. Garret Graves (R-LA) following the 2022 elections – radically redrawn in the 2024 map to become the second majority-black district currently represented by Rep. Cleo Fields (D-LA). However, the Supreme Court continues to consider whether the intentional creation of second majority-Black district constitutes an unconstitutional racial gerrymander.
Maryland: Earlier this month, Maryland’s House of Delegates passed legislation that would enact a new Congressional map. However, State Senate President Bill Ferguson has blocked the bill, arguing the window has closed to enact a new map ahead of the midterms and that a redraw could backfire by exposing Democrats to legal risks or a court-imposed map. Proposed redistricting would alter the lines of all eight of Maryland’s districts with the overarching goal of moving more liberal voters into Maryland’s 1st Congressional District, currently represented by the delegation’s lone Republican Rep. Andy Harris (R-MD).
New York: New York’s redistricting effort is currently in legal limbo after a state trial court judge struck down the redrawn boundaries of the 11th Congressional District currently held by Rep. Nicole Malliotakis (R-NY). The court has ruled that the new 11th Congressional District boundaries unconstitutionally dilute the voting power of Black and Latino residents. Rep. Malliotakis has escalated the issue to the U.S. Supreme Court, but if the court chooses not to intervene, New York’s Independent Redistricting Commission will be tasked with finalizing a new map before the April candidate filing deadline.
Utah: In Utah, a court-ordered Congressional map that creates a Democratic-leaning district in Salt Lake City is currently the law of the land but facing intense challenges from Republicans in state and federal courts. Recently, a federal court dealt Republicans a setback by denying the GOP’s request to block the new map. However, litigation continues. If the revised map holds, it could complicate Rep. Blake Moore’s (R-UT) reelection in Utah’s 1st Congressional District, which would be transformed from a safe Republican seat into a Democrat-leaning district.
Virginia: While Virginia had been headed towards an April 21 referendum on a redrawn map, a circuit judge recently acted to temporarily block the ballot question, creating tension with a Virginia Supreme Court decision to allow the referendum to proceed. The restraining order remains in effect until March 18, impacting early voting scheduled to begin on March 6. Democrats currently hold six of 11 House seats in the Virginia delegation. The proposed map could expand the split to a 10-1 advantage for Democrats. The districts most likely to flip based on the proposed redraw include Virginia’s 1st Congressional District currently held by Rep. Rob Wittman (R-VA), the 2nd Congressional District represented by Rep. Jen Kiggans (R-VA), the 5th Congressional District held by Rep. Bob Good (R-VA), and the 6th Congressional District represented by Rep. Ben Cline (R-VA).
Several other states – Indiana, Arkansas, Kansas, and Washington – recently pursued efforts to redraw their Congressional maps ahead of the midterm elections. However, these attempts have been unsuccessful or remain stalled. Other states – like Colorado – have more recently jumped into the redistricting fray and may have new maps in place after the midterms but before voters next head to the polls in 2028.
Snapshot of Key Races That Will Determine Control of the House
Arizona’s 1st Congressional District: Incumbent Rep. David Schweikert (R-AZ) is running for governor, creating an open-seat contest in an increasingly purple district. Both parties have crowded fields of candidates vying for the seat. Former Arizona Republican Party chair and early frontrunner Chair Gina Swoboda received President Trump’s endorsement but has since switched to the Secretary of State race, leaving former Arizona Cardinals kicker John Feely, former State Rep. Joseph Chaplik, and businessman John Trobought competing for the GOP nomination. Across the aisle, former Democratic State Rep. Amish Shah, who lost to Schweikert by less than four percent in 2024, is running again but faces primary challengers in businessman Jonathan Treble, former news anchor Marlene Galán Woods, and civil rights attorney Mark Robert Gordon, among others.

Arizona’s 6th Congressional District: Having won reelection with just 50 percent of the vote in 2024, incumbent Rep. Juan Ciscomani (R-AZ) has real cause for concern as polling continues to show a tight race in a district that has been won by less than one point in recent presidential elections. JoAnna Mendoza, a Marine Corps veteran, appears poised to clinch the Democratic nomination in the crowded primary. This race is seeing significant early financial activity. While Ciscomani held a cash advantage at the start of this year, Mendoza is quickly closing the gap.

California’s 22nd Congressional District: Incumbent Rep. David Valadao (R-CA) has held this seat since 2013 with a two-year gap after 2018. With the district lines changing because of California’s new Congressional map, Democrats are targeting this historically swing seat for a flip while Valadao aims to put some distance between himself and the president. On the Democratic side, State Assemblymember and physician Jasmeet Bains has emerged as a potential moderate choice while school board trustee and college professor Randy Villegas is drawing support from progressives ahead of the June 2 primary.

California’s 48th Congressional District: This district is viewed as a 2026 battleground following redistricting in the state. Incumbent Rep. Darrell Issa (R-CA) is seeking reelection despite the district shifting from a roughly 12-point Republican advantage to a four-point Democratic lead based on registration. The Democratic primary field is very crowded, though San Diego City Councilmember Marni von Wilpert appears to be consolidating support.

Colorado’s 8th Congressional District: After flipping the district red in 2024 by less than one point, incumbent Rep. Gabe Evans (R-CO) remains perhaps the most vulnerable GOP freshman. The Democratic primary has narrowed to three main contenders following the withdrawals of high profile figures like State Treasurer Dave Young and former Rep. Yadira Caraveo (D-CO). Marine Corps veteran and investment executive Evan Munsing, former State Rep. Shannon Bird, and current State Rep. Manny Rutinel are on track to face off in the June 30 primary.

Iowa’s 1st Congressional District: Rep. Mariannette Miller-Meeks’ (R-IA) seat remains a top Democratic pickup target after the narrowest GOP victory in the 2024 cycle, when the incumbent won her seat by only 799 votes. Christina Bohannan, a law professor making her third attempt for the seat and the likely Democratic nominee, remains neck-in-neck in fundraising with Miller-Meeks.

Iowa’s 3rd Congressional District: Incumbent Rep. Zach Nunn (R-IA) continues to pursue his reelection bid against a narrowing field of Democratic challengers. Running for his third term, Nunn has outpaced challengers on fundraising and recently received a visit from President Trump to bolster his campaign. Meanwhile, the field in the Democratic primary is getting smaller, with candidates withdrawing and throwing support behind State Sen. Sarah Trone Garriott.

Ohio’s 1st Congressional District: The 2026 race for this seat is a high-stakes frontline contest due to the major redistricting shift that has moved the seat from Democratic-favored to Republican-leaning. Despite the change in the district, incumbent Rep. Greg Landsman (D-OH) is seeking reelection and enters the race with a significant cash advantage. Four candidates have filed to run in the GOP primary, including sales professional Holly Adams, former Air Force and Central Intelligence Agency officer Eric Conroy, dentist Steven Erbek, and nonprofit founder Rosemary Oglesby-Henry.

Ohio’s 9th Congressional District: Incumbent Rep. Marcy Kaptur (D-OH) remains one of the most endangered House Democrats on the map, especially as Ohio continues to trend right and redistricting dynamics make running and winning in this district as a Democrat more challenging. Kaptur has represented the district for more than four decades, though President Trump carried the district by 6.5 points in 2024. Multiple Republican candidates are running to face off against Kaptur this November, including former Republican State Rep. Derrick Merrin who previously lost to Kaptur in the 2024 cycle, Ohio General Assembly Majority Whip Josh Williams, U.S. Air Force Reserve Lt. Col. Alea Nadeem, and healthcare professional Anthony Campbell.

Pennsylvania’s 7th Congressional District: Freshman Rep. Ryan Mackenzie (R-PA) flipped this district narrowly in 2024 and is running for reelection in what continues to be one of the most competitive districts in the country. The Democratic primary features a crowded field of contenders seeking to unseat Mackenzie. Candidates vying for the Democratic nomination include former federal prosecutor Ryan Crosswell, Northampton County Executive Lamont McClure, firefighter Bob Brooks, former PPL Electric Utilities executive Carol Obando-Derstine, Lehigh Valley Young Democrats vice president Aiden Gonzalez, and self-described “renegade Democrat” Lewis Shupe.

Pennsylvania’s 10th Congressional District: Rep. Scott Perry (R-PA) remains a uniquely polarizing incumbent who has repeatedly survived close races. Democrats are again attempting to consolidate support behind a challenger who can make the contest a referendum on Perry rather than a nationalized partisan contest. Former news anchor Janelle Stelson is seen as in the lead for the Democratic nomination, essentially making this contest a rematch of the 2024 election, which was decided by just 5,100 votes. Stelson has the backing of popular Gov. Josh Shapiro, while Perry has received Trump’s endorsement.

Washington’s 3rd Congressional District: Incumbent Rep. Marie Gluesenkamp Perez (D-WA) continues to outperform the partisan lean of her district and remains one of the most closely watched Democratic defenders in 2026. Because the district leans slightly Republican, the GOP is targeting this seat as just one of a few pickup opportunities. Washington uses a top two primary system where the two candidates with the most votes – regardless of party – will advance to the November ballot. This means Gluesenkamp Perez is most likely to find herself in a head-to-head matchup with prominent Republican candidate State Sen. John Braun.

Fundraising has been robust on both sides, evidencing the competitive nature of this race.

Conclusion
While we are still months out from the midterm elections, it is becoming increasingly clear there is an opportunity for Democrats to capitalize on historical trends and growing dissatisfaction with the current GOP trifecta in Washington amongst voters to flip the House in November. We have tried to highlight just some of the races where leading pundits seem to agree we are watching true tossups unfold, though there are many additional districts that have not yet been labeled as such. This suggests that candidate quality, fundraising, and local dynamics will determine whether today’s handful of competitive districts might expand the battlefield into a broader wave environment as Election Day nears.
